Therein lies the problem!
Inside your iniSo you need a Folder "OSTRe" with music-files
DataPath is D:\program files \ Final Fantasy 7\FINAL FANTASY VII\ficedula\
I'll give you the word If It actually works In like a hour >.>
Edit: perpetrated whaaa? If your asking why I have final fantasy 7 in a final fantasy 7 folder well I like my game folder's close and my Installer closer
Also In the FF7 Music.exe/configure/files there Is ostremix, custom, bootleg and mp3 remixed... I don't really get what most of these thing's do so what one do I pick?
